BRAYTON \VHEELER, OF SAGINAWV, MICHIGAN.

SPECIFICATION forming part of Letters Patent No. 342,888, dated June 1, 1886.

Application filed March J3, 1886. Serial No. 196,209. (No model.)

To all whom, it may concern.-

Be it known that I, BRAYION WHEELER, a citizen of the United States, residing at Saginaw city, in the county of Saginaw and State of Michigan, have invented a new and useful Improvement in Clamps for HoldingWellTubes and Poles, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in clamps for holding well tubes and poles; and it consists of the peculiar and novel construc tion and combination of parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The object of my invention is to provide an improved device for holding well tubes and poles while they are being connected or disconnected, and the invention is especially designed to be used in connection with the clamp patented to me on the 3d day of June, 1884:, No. 299,887.

In the accompanying drawings, Figure l is a perspective view of my invention in position upon a clamp of the class shown in the patent hereinbefore referred to. Fig. 2 is a detached perspective view of my invention, and Fig. 3 is a longitudinal cental sectional view thereof.

Referring to the drawings. in which like letters of reference denote corresponding partsin all the figures, A designates the clamp, which has the essential features of construction of the device shown in the patent hereinbefore referred to-namely, a slotted frame in which arejournaled the shafts carrying the biting dogs, the shafts being connected by a link or arm and having a lever,whereby the dogs can be simultaneously operated so that they can be caused to instantaneouslygrasp a well pole or tubethat is in danger of falling. The frame of this clamp has two vertical standards, B. which are bolted to the side pieces of the frame, and provided with a rectangular recess, 1), in their upper edges.

0 designates my invention, that is detachably mounted or fitted in the standards when it is desired to rigidly hold one section of a well tube or pole in connecting or removing it from another section.

My detachable holding device is provided with a flat plate or bar, D, having upwardlyextending flanges d, which form a space or posing faces, as at g.

ends of the standards B. The frame D carries a short standard, E, at each end, and each standard has a right-angled foot, 6, that bears on and is secured by bolts or the like to the lugs D of the frame, the side faces or edges of the standards being recessed, as at e, and bearing against the edges of the'standards B to steady and render the holder 0 rigid thereon. Each standard E has a threaded aperture or bearing, f, in which is fitted an adj usting-screw, F, which is provided at one end with a handle or crank or other suitable device for its convenient manipulation. The free ends of the adjusting-screws are provided with a rigid follower, f, and each of the screws work in a threaded bearing, g, in one of the adjustable dogs E, which are recessed at their inner op- The dogs are adj ustable between the'flanges of the frame toward and from each other, so that they can clamp tubes or poles of various diameters and with any degree of force.

The invention is very simple, strongand durable in construction, easily and readily adjusted to and detached from the standards B, is held very rigidly and firmly in place, the clamping orholding jaws can be adjusted very easily andindependently of each other, and the device can be manufactured very cheaply.

I do not desire to confine myself to the exact details of construction and form and proportion of parts herein shown and described as an embodiment of my invention, as I am aware that changes therein can be made.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ina device for-holding well tubes or poles, the combination,with a clamp, of the supporting standards, a frame det-achably secured therein, and the laterally-adjustable holdingjaws carried by the frame, substantially as described.
